About
The short version of a long career.
I got my first programming job at 19 — networking protocols at ITC Networks. Then I got into games at Ubisoft Bucharest, where I worked on Silent Hunter 5 and two Assassin's Creed titles.
After that I moved to City Interactive and shipped three more games (Sniper Ghost Warrior 2, Alien Rage, Enemy Front), mostly doing UI and multiplayer. I co-founded two indie studios along the way — Pixeldome for mobile and Secret Level, where we built Ironbound.
I also went back to Ubisoft for a bit as a Senior Unity Developer, worked on Eternium at Making Fun, and did consulting work on multiplayer systems.
Around 2021 I got into Web3. I was a core contributor at FIAT DAO and Loop Finance — oracle systems, CDP vaults, DeFi stuff deployed on multiple chains. Now I'm at Novel Labs building NFT ecosystems, cross-chain integrations, and governance tools.
Lately I've been spending more time on AI — drone detection pipelines, match prediction models, a prosthesis design tool, and looking into agent architectures for compliance automation.
Outside of work, my wife and I run Bucharest Westies — a West Coast Swing dance community we started about 15 years ago. Around 150 people now.

Web3 & Crypto
Smart contracts, NFT systems, DeFi protocols, and cross-chain tooling I've worked on.

AI & Agents
Things I've been building and exploring on the AI side.

Dance Companion
West Coast Swing pattern recognition using MediaPipe pose estimation. Extracts dancer poses from video and builds sequence models for feedback. Still early but the idea is close to home.

Not everything is code.
Bucharest Westies
West Coast Swing dance community — co-founded ~2011
My wife and I started learning West Coast Swing from DVDs because nobody was teaching it in Bucharest. So we started teaching it ourselves. That was about 15 years ago.
The community has grown to 80–150 active members. Level 1 is free for the first three months. Higher levels have an optional monthly fee — we don't enforce it. It's not really a business, more something we care about.
Running a community for this long has taught me a lot about consistency and showing up — probably more than most jobs have.
